It's definitely possible to have Peyronie's without palpable plaque, or even plaque noticeable on ultrasound. Congenital curves can put you at more risk for Peyronie's, and in the end, a new curve is serious!

i cant remember if i used to have it since birth or not, the strange thing is that when iam fully erect the curve is about 10 to 15 degree along the whole shaft otherwise the curvature is bigger, no pain no plaque!!
